Wound Care Certification Exam Wound Care Certification Pressure Injury Prevention 2 — Questions and Answers
Question 1: A patient with a Stage 3 pressure injury has a BMI of 16.2 and serum albumin of 2.1 g/dL. Which nutritional intervention is MOST appropriate to support wound healing?
- Restrict protein to 0.8 g/kg/day to prevent renal strain
- Provide 1.25–1.5 g/kg/day protein with caloric supplementation (Correct answer)
- Initiate parenteral nutrition immediately regardless of GI function
- Supplement with vitamin C only and recheck albumin in 4 weeks
Correct answer: Provide 1.25–1.5 g/kg/day protein with caloric supplementation
Malnourished patients with pressure injuries require 1.25–1.5 g/kg/day protein and adequate calories to support tissue repair.
Question 2: Which Braden Scale subscale directly measures the patient's ability to change and control body position?
- Moisture
- Activity
- Mobility (Correct answer)
- Friction and Shear
Correct answer: Mobility
The Mobility subscale assesses the patient's ability to change and control their body position independently.
Question 3: A critically ill patient in the ICU is placed on a vasopressor. How does this medication increase pressure injury risk?
- It increases urine output, causing moisture-related skin breakdown
- It causes peripheral vasoconstriction, reducing tissue perfusion to bony prominences (Correct answer)
- It raises core body temperature, accelerating skin breakdown
- It causes agitation, increasing friction and shear forces
Correct answer: It causes peripheral vasoconstriction, reducing tissue perfusion to bony prominences
Vasopressors cause peripheral vasoconstriction, which reduces blood flow to skin over bony prominences and increases ischemia risk.
Question 4: Which support surface feature is MOST important for a patient with a pressure injury on the sacrum who is fully dependent for repositioning?
- Low air-loss capability to manage moisture
- Alternating pressure to cyclically relieve pressure (Correct answer)
- Lateral rotation to prevent pulmonary complications
- High-density foam for cost-effective immobility support
Correct answer: Alternating pressure to cyclically relieve pressure
Alternating pressure surfaces cyclically relieve pressure and are recommended for high-risk patients who cannot reposition themselves.
Question 5: A nurse notices a dark purple discoloration on an intact heel of a patient admitted 6 hours ago. The area is firm and painful. This finding is BEST classified as:
- Stage 1 pressure injury
- Stage 2 pressure injury
- Deep tissue pressure injury (DTPI) (Correct answer)
- Unstageable pressure injury
Correct answer: Deep tissue pressure injury (DTPI)
Deep tissue pressure injury presents as intact skin with non-blanchable dark purple or maroon discoloration indicating injury to underlying soft tissue.
Question 6: When repositioning a patient to prevent pressure injury, which technique BEST reduces shear forces?
- Elevating the head of bed to 90 degrees before turning
- Using a draw sheet or friction-reducing slide sheet to move the patient (Correct answer)
- Rolling the patient directly across the mattress surface
- Asking the patient to push with their heels during repositioning
Correct answer: Using a draw sheet or friction-reducing slide sheet to move the patient
Friction-reducing slide sheets minimize the shear and friction forces applied to skin during repositioning.
Question 7: According to NPUAP/EPUAP guidelines, what is the MAXIMUM recommended head-of-bed elevation for patients at risk for pressure injuries, unless medically contraindicated?
- 15 degrees
- 30 degrees (Correct answer)
- 45 degrees
- 60 degrees
Correct answer: 30 degrees
The head of bed should be maintained at 30 degrees or less to minimize shear forces on the sacrum and coccyx.
